How to implement basic trigonometric functions (arc sine, arc cosine, arc tangent) in Go?

To implement basic trigonometric functions (arc sine, arc cosine, arc tangent) in Go, you can use the math package from the standard library. Here's an example of how to implement these functions:

package main

import (
	"fmt"
	"math"
)

func main() {
	angle := math.Pi / 4 // angle in radians

	// Arc sine (inverse sine)
	asin := math.Asin(angle)
	fmt.Println("Arc sine:", asin)

	// Arc cosine (inverse cosine)
	acos := math.Acos(angle)
	fmt.Println("Arc cosine:", acos)

	// Arc tangent (inverse tangent)
	atan := math.Atan(angle)
	fmt.Println("Arc tangent:", atan)
}

This code snippet calculates the arc sine, arc cosine, and arc tangent of an angle (π/4 or 45 degrees in this case) using the math.Asin(), math.Acos(), and math.Atan() functions, respectively.

Note that the trigonometric functions in Go work with radians, so make sure to convert the angle to radians if you're working with degrees. You can use the math.Pi constant to represent the value of π.
